check your vacuum line and the electrical systems
SOURCE: 2001 focus. Replaced plugs, wires and coil pack.
Have you replaced the timing belt? if not i would highly recommend doing so. these cars need to have the timing belt replaced before it breaks otherwise it can and will cause major engine damage.

Have you checked your camshaft sensor? It's possible that the vane on the Synchronizer is misaligned.

Hi,
First of all I would like to start with this bit of information for you. Most scan tools will not pick up fault codes on a 7.3L diesel. I keep an Actron pocket code reader with me at work to diagnose the gas engines, but when it comes to the diesels I have to use the Ford IDS system to get fault codes. I can't explain why, but thats just how it is.
Now on to your problem........... Without fault codes to go by, I am going to make an educated guess as to what is happening to your engine based on the most common concerns I see with these engines. My guess (based on your description of the concern) would be that one of the fuel injector wiring harnesses located under the left or right valve covers is becoming dislodged. I see this alot and as a matter of fact I just repaired one this past friday.
Since we dont have a fault code to tell us which bank has the bad connection, you will have to remove both valve covers and check where the wiring connects to the valve cover gasket. These connectors, over time, tend to loosen and move away from the valve cover gasket connector causing you to lose up to 4 cylinders, when the engine cools down a bit they regain the connection and work fine. The connectors don't have to move much either for this to happen.
You can go to Ford and buy a new under the valve cover harness for $$$ or you can simply install a plastic wire tie to keep the connector in place. The choice is yours. I would also like to add that if you do this job yourself you will have to remove the big intake hoses that go from your intercooler to the engine. It is critical that you clean the ends of these tubes to remove any oil residue before reinstalling them. You also want to torque the tube clamps to 18 ft lbs when you reinstall. Tighter is not better, they will blow off under pressure.
I also want to add that your truck was involved in a recall (07S57) for the camshaft position sensor. If it hasn't been replaced yet call your Ford dealer with your vin number and ask about it. When this cmp sensor goes bad it will shut the engine off leaving you stranded.
I hope some or all of this helps you!
